Once the source is located, attempt to attenuate the EMC coupling path by
distancing the defibrillator from the source as much as possible. If assistance
is needed, call your local service representa ti ve.
Restrictions for Use
Artifact on the ECG caused by electromagnetic interference should be evalu-
ated by a physician or physician authorized personnel to determine if it will
negatively impact patient diagnosis or treatment.
Immunity Level
The EMC standards state that manufacturers of patient-coupled equipment
must specify immunity levels for their systems. It is recog nized tha t the Heart -
Start XLT defibrillator/monitor is designed to receive and amp lif y low level
signals in the same bandwidth as the interf erence.
Immunity is defined in the standard as th e ability of a system to perform with-
out degradation in the presence of an electromagnetic disturbance. Degrada-
tion in ECG quality is a qualitative assessment which can be subjective.
Caution should, therefore, be taken in comparing immunity levels of diffe rent
devices. The criteria used for degradation is not specified by the standard and
may vary with the manufacturer.
